CompTIA A+ Exam Overhaul: Key Differences Between 220-1001/1002 and 220-1101/1102

The CompTIA A+ certification has long served as the foundational credential that launches countless careers in information technology. As the most widely recognized entry-level IT certification in the industry, it validates the core hardware, software, networking, and troubleshooting skills that employers expect from IT support professionals at the beginning of their careers. CompTIA periodically revises the examination to ensure its content remains aligned with the evolving technology landscape, and the transition from the 220-1001 and 220-1002 examination series to the 220-1101 and 220-1102 series represents one of the most significant updates the certification has undergone in recent years.

For candidates who are deciding which version of the examination to pursue, or for professionals who hold the older credential and want to understand how the updated examination reflects changes in the field, understanding the specific differences between these two examination generations is genuinely important. The update is not merely cosmetic. It reflects substantive changes in the technologies that IT support professionals encounter in their daily work, the skills that employers prioritize when hiring for support roles, and the broader direction in which the IT support profession is evolving. This guide examines those differences in depth, providing the clear and comprehensive comparison that candidates and professionals need to make informed decisions about their certification journey.

Why CompTIA Updates Examinations and What Drives the Changes

CompTIA follows a defined examination development process that involves regular review of certification content to ensure it remains relevant to current industry needs. This process includes job task analysis surveys conducted with IT professionals and employers, review of industry trends and technology adoption patterns, and consultation with subject matter experts who provide guidance on what knowledge and skills are genuinely required for effective performance in the roles the certification targets. The results of this analysis drive decisions about what content to add, remove, or restructure in updated examination versions.

The transition from the Core Series 1000 examinations to the Core Series 1100 examinations was driven by several significant shifts in the IT support landscape. The acceleration of cloud adoption across organizations of all sizes changed the nature of the infrastructure that IT support professionals interact with and the problems they are asked to solve. The proliferation of mobile devices and the growing diversity of operating systems in enterprise environments expanded the range of platforms that support professionals must be competent to manage. The increasing prominence of cybersecurity as a concern at every level of IT work, including frontline support, elevated the security knowledge expectations for entry-level professionals. Each of these shifts is reflected in the content changes between the two examination generations.

Core Structure Comparison Between the Two Examination Generations

Both the 220-1001 and 220-1101 examinations serve as the first of the two required assessments for the CompTIA A+ certification, covering hardware, networking, mobile devices, and cloud computing fundamentals. Similarly, both the 220-1002 and 220-1102 examinations serve as the second required assessment, covering operating systems, security, software troubleshooting, and operational procedures. This structural parallel makes the comparison between generations relatively straightforward, as changes can be analyzed by comparing corresponding examinations within each series.

The 220-1001 examination was organized around five domains: Mobile Devices, Networking, Hardware, Virtualization and Cloud Computing, and Hardware and Network Troubleshooting. The updated 220-1101 examination maintains a similar five-domain structure but reorganizes and relabels domains in ways that reflect shifting emphasis and content priorities. The 220-1002 examination covered four domains including Operating Systems, Security, Software Troubleshooting, and Operational Procedures, while the 220-1102 examination maintains these same four domain areas but with updated content that reflects the evolved security landscape and the changing mix of operating systems that support professionals encounter. Understanding both the structural continuity and the specific content changes within this overall structure is the starting point for a meaningful comparison between the two examination generations.

Hardware Domain Changes and Updated Technology Coverage

The hardware domain has always been central to the CompTIA A+ examination, and the transition from the 1001 to the 1101 series brought meaningful updates to the hardware content that reflect changes in the physical technologies that IT support professionals work with regularly. One of the most notable areas of change involves storage technologies, where the updated examination places greater emphasis on solid state drive technologies and the various form factors and interface standards associated with them. The older examination covered solid state drives alongside traditional hard disk drives in a relatively balanced way, while the updated examination reflects the reality that solid state storage has become the dominant storage technology in modern client computing devices.

Memory technology coverage also evolved between the two examination generations, with the 1101 series incorporating updated content on current memory standards and configurations that were less prominent or nonexistent when the 1001 series was developed. Display technology coverage was similarly updated to reflect the proliferation of new display standards and connection types that have become common in modern computing environments. The treatment of peripheral devices and connection interfaces was revised to reflect the growing dominance of USB-C and Thunderbolt connections alongside the declining prevalence of older interface standards that received more attention in the 1001 series. These hardware updates collectively ensure that candidates are being assessed on knowledge that is directly applicable to the devices they will actually encounter in support roles rather than equipment that is increasingly rare in modern environments.

Networking Content Evolution and Modern Connectivity Focus

Networking has been a consistent component of the CompTIA A+ examination throughout its history, and the transition from the 1001 to the 1101 series brought updates that reflect the changing nature of network connectivity in enterprise and small business environments. The updated examination places greater emphasis on wireless networking technologies, reflecting the continuing shift toward wireless connectivity as the primary network access method for an increasing proportion of devices in modern environments. Coverage of current wireless standards, including more recent generations of the wireless networking protocol family, was updated to ensure alignment with the wireless technologies actually deployed in contemporary environments.

Cloud networking concepts received expanded treatment in the 1101 series compared to the 1001 series, reflecting the growing importance of cloud-based services in the environments that IT support professionals support. The older examination addressed virtualization and cloud computing in a dedicated domain, but the updated examination integrates cloud-related networking concepts more thoroughly throughout the networking content rather than treating cloud as a separate and somewhat isolated topic. This integration reflects the reality that cloud connectivity has become a routine aspect of enterprise networking rather than a specialized area that only certain IT professionals encounter. Internet of Things connectivity concepts also received updated treatment in the 1101 series, acknowledging the growing prevalence of connected devices in both enterprise and consumer environments that IT support professionals may be asked to assist with.

Mobile Device Coverage and Cross-Platform Support Skills

Mobile device support has been part of the CompTIA A+ examination since the 1001 series, but the specific devices, operating systems, and management approaches covered in the examination have evolved significantly between the two generations. The 1101 series updated its mobile device content to reflect the current distribution of mobile platforms in enterprise environments, including updates to coverage of iOS and Android that reflect the current versions and capabilities of these platforms rather than the older versions that were current when the 1001 series was developed.

Mobile device management concepts received expanded attention in the 1101 series, reflecting the growing adoption of formal mobile device management solutions in enterprise environments of all sizes. The older examination addressed mobile device management at a relatively basic level, while the updated examination tests more detailed knowledge of how mobile device management solutions are used to enforce security policies, manage application deployment, and support remote wipe and lock capabilities for devices that may contain sensitive organizational data. Synchronization and connectivity concepts for mobile devices were also updated to reflect current practices, including how mobile devices connect to enterprise services and how data synchronization works across the range of platforms and services that modern organizations use.

Virtualization and Cloud Computing Domain Restructuring

The treatment of virtualization and cloud computing represents one of the more significant structural changes between the two examination generations. In the 220-1001 examination, virtualization and cloud computing formed a distinct fifth domain that was relatively compact compared to the other four domains. The updated 220-1101 examination integrated cloud computing concepts more thoroughly throughout the examination rather than isolating them in a separate domain, reflecting the assessment that cloud knowledge is now a pervasive requirement across multiple areas of IT support work rather than a specialized topic area.

Cloud computing service models including Infrastructure as a Service, Platform as a Service, and Software as a Service received updated treatment in the 1101 series that reflects their current prevalence and the specific ways that IT support professionals interact with cloud-based services in their daily work. The practical support implications of cloud adoption, including how troubleshooting approaches differ for cloud-hosted services compared to on-premises systems and how connectivity to cloud services is managed and diagnosed, received greater attention in the updated examination. Client-side virtualization concepts, including how virtual machines are used in enterprise environments and the support considerations associated with virtualized desktop environments, were also updated to reflect current virtualization practice rather than the virtualization approaches that were more common when the 1001 series was developed.

Operating System Coverage Updates in the Second Examination

The operating system domain, covered primarily in the second examination of each series, underwent significant updates between the 1002 and 1102 generations. One of the most notable changes involves the treatment of Windows operating system versions. The 220-1002 examination covered Windows versions that were current or recently supported at the time of its development, while the 220-1102 examination updated this coverage to reflect the current Windows landscape, including the features and administrative approaches associated with Windows versions that have become dominant in enterprise environments since the earlier examination was developed.

The 1102 series also updated its treatment of macOS and Linux operating systems, reflecting the growing prevalence of these platforms in enterprise environments where they were historically less common. The older examination addressed macOS and Linux as secondary platforms with relatively limited coverage, while the updated examination acknowledges that IT support professionals increasingly encounter these operating systems in their daily work and must be competent to support users on these platforms rather than treating them as unusual edge cases. Command-line interface skills for both Windows and Linux environments received updated coverage in the 1102 series, reflecting the growing importance of command-line competency for IT support professionals who work in environments where scripting and automation are increasingly used for system management tasks.

Security Domain Expansion and Threat Awareness Updates

Security content underwent some of the most substantive updates between the 1002 and 1102 examination generations, reflecting the elevated importance of security awareness and practice at every level of IT work. The 220-1002 examination included a security domain that covered foundational security concepts, common threats, and basic security practices. The updated 220-1102 examination expanded this security content significantly, reflecting the reality that frontline IT support professionals are now expected to play a more active role in organizational security than was typical when the earlier examination was developed.

The updated security domain covers a broader range of threat types and attack vectors, including social engineering techniques that target end users and that IT support professionals must be able to recognize and respond to appropriately. Phishing, vishing, and other social engineering attacks have become among the most common vectors for security incidents in organizational environments, and IT support professionals who interact directly with end users are often among the first to encounter reports of these attacks. The 1102 series also updated its coverage of endpoint security practices, including more detailed treatment of how security software is deployed and managed, how data encryption is implemented on client devices, and how security policies are enforced through technical controls. Physical security concepts, including how IT support professionals contribute to physical access control and how to recognize and respond to physical security concerns, received expanded coverage in the updated examination.

Operational Procedures and Professionalism Content Updates

The operational procedures domain, which covers the professional skills and workplace practices that complement technical knowledge in IT support roles, underwent meaningful updates between the two examination generations. The 220-1002 examination covered topics including documentation practices, change management procedures, disaster recovery concepts, and professional communication skills. The 220-1102 examination updated this content to reflect evolving workplace practices and the changing professional context of IT support work.

Remote support procedures received significantly expanded coverage in the 1102 series, reflecting the dramatic growth in remote work and the corresponding need for IT support professionals to provide effective assistance to users who are not physically present in a central office location. The older examination addressed remote support tools and techniques at a basic level, while the updated examination tests more comprehensive knowledge of how remote support is conducted effectively, including the tools, techniques, and professional practices that make remote support productive for both the support professional and the user being assisted. Environmental and safety considerations were also updated in the 1102 series, with coverage that reflects current best practices for responsible handling of electronic components, hazardous materials, and equipment disposal in ways that comply with current environmental regulations and organizational policies.

Troubleshooting Methodology and Practical Problem-Solving

Both examination generations emphasize systematic troubleshooting as a core competency for IT support professionals, and the troubleshooting content was updated between the two series to reflect both changes in the technologies being troubleshot and evolving best practices for the troubleshooting process itself. The CompTIA troubleshooting methodology, which provides a structured approach to diagnosing and resolving technical problems, remains a central concept in both examination generations, but the specific scenarios and symptoms used to test troubleshooting knowledge were updated to reflect the current technology landscape.

Hardware troubleshooting scenarios in the 1101 series reflect the updated hardware technologies covered elsewhere in the examination, testing candidates on diagnostic approaches for current storage, memory, display, and connectivity technologies rather than legacy hardware that is increasingly rare in modern environments. Network troubleshooting content was updated to address the connectivity scenarios that arise in environments with greater reliance on wireless networking and cloud-connected services. Operating system troubleshooting scenarios in the 1102 series reflect the updated operating system coverage, including troubleshooting approaches for the current Windows versions and the macOS and Linux platforms that now receive more substantial coverage in the updated examination.

Examination Weight Distribution and Domain Emphasis Shifts

Beyond the specific content changes within each domain, the distribution of examination weight across domains shifted between the two examination generations in ways that reflect the changing priorities of the IT support profession. In the 220-1001 examination, Hardware and Network Troubleshooting carried the largest single domain weight, reflecting the historical centrality of hardware diagnosis and repair in IT support work. The 220-1101 examination adjusted these weights to give greater relative emphasis to networking and cloud computing content, acknowledging the shifting nature of the technical challenges that IT support professionals spend the most time addressing.

In the second examination, the security domain received increased weighting in the 220-1102 compared to the 220-1002, reflecting the elevated security expectations for entry-level IT professionals discussed earlier in this guide. This weight increase means that candidates who underinvest in security preparation face a proportionally greater risk of failing the updated examination compared to the older one, making security content a priority area for any serious 1102 candidate. The operational procedures domain maintained a relatively consistent weight between the two generations, reflecting the stable importance of professional skills and workplace practices even as the specific content within the domain was updated.

Choosing Which Examination Version to Pursue

For candidates who are beginning their CompTIA A+ journey today, the choice is straightforward. The 220-1001 and 220-1002 examinations reached their retirement date, and candidates who want to earn the CompTIA A+ certification must pursue the current 220-1101 and 220-1102 series. Choosing the current series also ensures that the credential earned reflects knowledge of current technologies rather than an older generation of the examination whose relevance will diminish more quickly as the retirement date of the older series recedes further into the past.

For candidates who were partway through the older series when the transition occurred, the decision was more complex and depended on timing and individual circumstances. Those who had passed one of the older examinations but not yet completed the second had to evaluate whether to complete the older series before its retirement deadline or to switch to the newer series and start fresh. This situation is less commonly relevant at this point, as the transition period has passed, but understanding how CompTIA handles examination transitions is useful background knowledge for any professional who expects to pursue additional CompTIA certifications in the future and may face similar transition decisions with other credentials in the CompTIA portfolio.

Conclusion

The transition from the CompTIA A+ 220-1001 and 220-1002 examinations to the 220-1101 and 220-1102 series represents a substantive and meaningful update to one of the most important entry-level credentials in the information technology field. This guide has examined the specific differences across hardware, networking, mobile devices, cloud computing, operating systems, security, operational procedures, and troubleshooting content, providing a comprehensive comparison that illuminates both what changed and why those changes reflect genuine shifts in the IT support profession.

The overarching theme of the examination update is alignment with the current reality of IT support work rather than the reality that existed when the older series was developed. Modern IT support professionals work in environments where cloud services are ubiquitous, where wireless connectivity is often the primary network access method, where security awareness and practice are expected at every level of the organization, where remote support capabilities are essential rather than optional, and where a broader range of operating systems and device types must be supported than was typical in previous generations of the enterprise environment. The 220-1101 and 220-1102 examinations test knowledge that is directly relevant to this current reality, making them more valuable as preparation tools and more meaningful as credentials than an older examination series would be.

For candidates who are approaching the CompTIA A+ certification for the first time, the updated examination series provides an excellent foundation for an IT support career built on knowledge that reflects how the profession actually operates today. The preparation process for these examinations, while demanding, builds a comprehensive body of knowledge that extends well beyond what is strictly necessary to pass the assessment, providing a practical understanding of the technologies and practices that will serve IT professionals throughout the early years of their careers. The investment made in thorough, systematic preparation for the 220-1101 and 220-1102 examinations pays dividends not just in examination success but in the genuine professional capability that makes an IT support professional effective and valuable from their very first day on the job.
